Change the text color of all links using JavaScript

Thanks,

That's what I was afraid of.

So, I'm trying to use the script below and underline every link in blue but I can't get the LineStyle syntax correct.
What is the correct syntax for that?

for (var p=0; p<this.numPages; p++) {
var box = this.getPageBox("Crop", p);
var links = this.getLinks(p, box);
if (links==null || links.length==0) continue;
for (var i in links) {
links[i].borderColor = color.blue;
links[i].borderWidth = 1;
links[i].LineStyle = "Underline";  
}
}
